Form control description-Printer options-Non-resizable-Contains check boxes.-Buttons to open system printers window and select printers-Form control is by AcuTerm GUI

Issue-Intermittently when opened the entire form shrinks to the width of about 1 inch.-App hangs. Need to use task manager to terminate.

Knowns and Unknowns-Multiple Windows 7 32 bit computers affected.-I have not witnessed it myself nor was able to reproduce but have a screen shot provided by the end-user.-Event viewer does not have any warnings/errors that could be dimmed as related.-No issues with printers as far as I know.-Only one form does it.-No recent changes/updates in the system except the offending app which was updated a few months ago.
